Hi, All.
I have a well which was originally badly 'outfitted', (not me!), and now I need to improve it.
The well is a cased bore 16cms diameter, and is about 75 feet deep. The water has then to be pumped uphill to the house through a vertical distance of about 50 feet. (the actual pipe run is about 350 feet). The original installation was a deep well pump, with a pressure tank fitted at the head of the well. In general, when it was working, it was reasonably good, but had a number of problems. This all came to a head a few days ago when we found the cast iron pump housing had frozen, resulting in a large crack.
I have been considering changing to a submersible pump for a long time, but have no experience of them, so maybe I can get some help here please?
1) What size pump do I need for the above well, or how do I calculate what I need - flow rate is not an issue, because the water can be pumped slowly to a reservoir tank before use - ie the water is not used 'online'
2) I have read a lot of conflicting information about torque arrestors and/or spiders, ranging from 'definitely fit this' to 'never fit this', often no reason given. What should I do?
3) I would like to keep the existing system after the pressure tank - in other words, simply fit a pipe down the well with the sub pump on the end - any reasons why not?
Thanks.
